Quartz的用法实例一

      1. javabean类
                  在Test.QuartzJob中

           package Test;

           public class QuartzJob {
              public void work()
              {
                    System.out.println("Quartz的任务调度！！！");
                 }
            }

      2. 设置Spring的xml
            我新建了一个applicationContext_quartz.xml，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd">


        <!-- 要调用的工作类 -->
        <bean id="quartzJob" class="Test.QuartzJob"></bean>
        <!-- 定义调用对象和调用对象的方法 -->
        <bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
            <!-- 调用的类 -->
            <property name="targetObject">
                <ref bean="quartzJob"/>
            </property>
            <!-- 调用类中的方法 -->
            <property name="targetMethod">
                <value>work</value>
            </property>
        </bean>
        <!-- 定义触发时间 -->
        <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
            <property name="jobDetail">
                <ref bean="jobtask"/>
            </property>
            <!-- cron表达式 -->
            <property name="cronExpression">
                <!-- 每隔10秒执行一次-->
                <value>0/10 * * * * ?</value>
            </property>
        </bean>
        <!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 -->
        <bean id="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
            <property name="triggers">
                <list>
                    <ref bean="doTime"/>
                </list>
            </property>
        </bean>
 
</beans>

       3. 设置web.xml对Spring加载

<!-- 加载spring -->
<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>
    /WEB-INF/classes/applicationContext*.xml
   </param-value>
</context-param>
<servlet>
   <servlet-name>context</servlet-name>
   <servlet-class>
    org.springframework.web.context.ContextLoaderServlet
   </servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>

注意：1.导入quartz-all-1.5.2.jar  下载http://download.csdn.net/source/1026766
           2.导入spring.jar（我用的是spring2.0以前的版本）  下载http://download.csdn.net/source/1041819
              如果不导入的话
               org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean
              org.springframework.scheduling.quartz.CronTriggerBean
              org.springframework.scheduling.quartz.SchedulerFactoryBean
              spring中的这三个类找不到，spring不能正常加载，由于第一次使用Quartz，我就是当时忽略了这一点，浪费了很多时间来调配置，其实配置一点没有错误。
            3. 你会问为什么用spring后就不用
                quartz.properties
                quartz-jobsxml  
                这两个文件了么？
                我回答：是的，它会自动找到quartz包中默认的这两个文件，如果你有特殊需要，也可以自己定义这两个文件。

附：quartz.properties
#
# Configure Main Scheduler Properties
#

org.quartz.scheduler.instanceName = TestScheduler
org.quartz.scheduler.instanceId = one

#
# Configure ThreadPool
#

org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 5
org.quartz.threadPool.threadPriority = 4

#
# Configure JobStore
#

#org.quartz.jobStore.misfireThreshold = 5000

#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore

# ===========================================================================
# Configure SchedulerPlugins ===============================================
# ===========================================================================
#org.quartz.plugin.triggHistory.class = org.quartz.plugins.history.LoggingTriggerHistoryPlugin
#org.quartz.plugin.triggHistory.triggerFiredMessage = Trigger {1}.{0} fired job {6}.{5} at: {4, date, HH:mm:ss MM/dd/yyyy}
#org.quartz.plugin.triggHistory.triggerCompleteMessage = Trigger {1}.{0} completed firing job {6}.{5} at {4, date, HH:mm:ss MM/dd/yyyy} with resulting trigger instruction code: {9}

org.quartz.plugin.jobInitializer.class = org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName =quartz_jobs.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = false
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

org.quartz.plugin.shutdownhook.class = org.quartz.plugins.management.ShutdownHookPlugin
org.quartz.plugin.shutdownhook.cleanShutdown = true
系统会根据配置文件找到quartz_jobs.xml
